[Minios-devel] [UNIKRAFT PATCHv6 05/37] plat: Add variables in Config.uk for early debug console

[Wei Chen <wei.chen@xxxxxxx>]

Instead of hardcoding, we provide Kconfig variables for users
to enable early debug console and UART base address of early
debug console.

As both ukplat_coutk and ukplat_coutd will use the PL011 UART
to print messages. But I still want to make EARLY_PRINT_PL011_UART_ADDR
depend on KVM_DEBUG_SERIAL_CONSOLE. Because I think before
ukpalt_init_console, only ukplat_coutd is avaibale, if we call
ukplat_coutk, we can't confirm it can be succeeded.
